Database design - boolean attribute or new table

Question

Let\'s say I have a database table that I want to filter based on a boolean attribute (for example, \"flagged\" attribute). Is it better to just add a \"flagged\" attribute

Answer 1

If this flag has attributes by itself or if it is reusable, better create it as another table. But if its just something to mark a row as true/false, just make a bool column(and save time and work effort)
